The present study fabricated a series of capillary wicks for loop heat pipes(LHPs),using two different methods,the cold-pressing sintering and direct loose sintering,and experimentally investigated the effect of different methods,compositions and sintering parameters on their properties in terms of porosity,permeability and pore radius.Porosity and pore radius were measured by the Archimedes method and Scanning Electron Microscope(SEM),respectively.Permeability of the wicks was compared by calculation using empirical equation.Results show that capillary wicks were successfully fabricated by using two different methods;the optimal capillary wick was found to be sintered at 650℃ for 30min,using direct loose sintering technique,with 90% nickel and 10% copper.The wicks could reach the porosity of 70.07% and the permeability of 10-13m2 order,with mean pore radius of 0.54μm.
